FILLING ATTACHIIIENT.

Specification of Letters-Patent.

Patented April 28, 1908.

Application led March 17, 1906. Serial No. 306,604.

To all whom it may concer/it: p

Be it known that 4I, `EDWARD N. ROTH, a citizen of the United States, residing at Chi-` cago, in the county of Cook and State of Illi no1s, have invented certain new and useful Im roveinents in Filling Attachments, of which the followin is a specification.

My invention re ates to improvements in filling attachments, and is especially adapted for use as a filling attachment f'or the eX- pansion-drum of a hot-water car-heating system.

The object ofmy invention is to provide a device of the character described, in which the possibility of dust, cinders and the like findlng their way into the valve mechanism, when the device is not in use as a filler, is obviated, and which shall be of simple and inex ensive construction.

hese, and such ,other objects as may hereinafter ap ear, are attained b my invention, a pre erred embodiment ot which is shown in,the accom anying drawings, in which like reference c aracters indicate the same arts throughout. i

'In t e drawings, Figure 1 is a longitudinal section through the a paratus, showingt'he funnel in its upturne position, or the position which the same will assume when the' device is being used as a iiller. Fig. 2 is a vertical, cross-sectional view, the section being taken on the line 2 2 of Fig. 1, looking ill the directionindicated by the arrows. Fig.

3 shows a vertical cross-section on the line 3-3 of Fig. 1, looking in the direction indicated by the arrows.

In the several iigures of the drawings, A is a castin forming a valve casing and having a forward y extending neck B and a rearwardly extendin neck C. Leadin inwardly through the nec C isa passa e opening into a valve chamber E. leading out-4 wardly from the valve chamber E, through` the neck B, is a water passage F and a vent or air passage G. The end of the neck B is screw-threaded for attachment to an eXpansion-drum, or other connection. The u per part of the valve chamber E is closed )y a ca or bonnet H, through which extends the va ve stem I, which carries upon its inner end the valve piece J and upon lts outer end the hand-wheel K. The valve stem I 'is provided with screw-threads adapted to engage screw-threads upon the bonnet H. The rotation of the hand-wheel K and valve stem I in one direction carriesl the valve `stern inwardly and causes the valve-piece J to seat itself upon the. valve-seat L. Communication between the passages D and F is thus shut off. -Rotation of the valve stem and hand-wheel in theopposite direction moves vthe vvalve piece J` away from its seat L and establishes communication between the passages D and F.

The outer end of the neck C is interiorly screw-threaded. The filling funnel M is provided with a neck N, this neck N being exteriorly screw-threaded for connection with the screw-threaded` neck C ofthe casting A. Nearthe outer end of the 'neck C the latter is interiorly provided with 'a lip O depending from the upper Wall of the passage D and lforming a partition extending slightly more than half-way acrossthe assage. The opening P is thus restricte to a semi-circular form, as clearly shown in Fig. 2. The o ening Q, through the end of the funnel-nec N, is similarly restricted to a semi-circular form, asshown in Fig. land Fig. 3. These openings P and Q, as thus formed, are adapted to register with each other when the fun# nel is in the upturned position, as shown in Fi 1 and to be out of register when the funne is inverted. To limit the rotation of the funnel and prevent its becoming unscrewed and separated from the castin A, I provide the neck of the funnel with a clieck-screw R, `and cut away the neck C at its end, as shown in Fig. 3, so as to form shoulders S and T against which the screw R may abut. The funnel is thus permitted to have a rotary movement through substantially yone-half a revolution. When at the limit of its rotation in one direction, the open mouth of the funnel is upward and a continuous passage is provided from the funnel into the casing A. When the funnel is at the limit of its rotation in the other direction the mouth of the funnel is down and the* assage from the funnel into the casing A is c osed.

The operation of the device may be described as follows: When it is desired to fill the expansion-drum, or other connection, the funnel `M is turned upwardly and the valve` opened by rotating the hand-Wheel K and valve stem I. Water being poured into the. funnel will iind its way into the passage D and thence through the valve chamber E` to the passage F, whence itwill flow out through the open end of said passage. As the water latter assuming the position shown in Fig. 4. The passa e leadin from Ythe funnel into the casing is t ereby c osed and the entrance of dust, cinders, etc. into the valve e'lectuallyV Y prevented. In devices of this class, as heretofore constructed, considerable trouble has been experienced by reason of the fact that dirt and cinders could iind their Way into the valve chamber, preventing the perfect seating of the valve and otherwise interfering With the perfect working of the device. By

The va ve may now be closed and thel funnel inverted, thel i sese he use of my invention I am enabled to {Li-l0- vide a form of filling attachment in w 'cli this source of trouble is eliminated.

I claim:

In a filling device, the combination with a casing having a iiuid passa e-Way therethrough, of a partition at t e end of said passage'- Way and closing the upper half thereof, a funnel, said funnel having a neck at substantially right angles to the funnel, said neck being rotatably connected with the casing andv provided with a thickened lpart wed e shaped in longitudinal section W ich lies ehind said partition when the funnel is in its upright position and which obstructs the passa e from the funnel to the casing when the Iunnel is inverted.
